[GiNaC-list] Debugging with GiNaC

Hi all, I'm trying to debug with GiNaC objects. I am aware of the dbgprint() function, however, this function can't be found for a numeric or a symbol. GiNaC::basic has this function, but it can't be found for numeric or symbol. The strange thing also is that gdb can't find any function listed in the class reference of, say, numeric. So the basic question is: How can i print the contents of GiNaC::numeric and GiNaC::symbol while debugging? Thank you very much, kind regards, Patrick
